17-4PH Alloy is a precipitated, hardened, martensitic stainless steel consisting of copper, niobium/columbium.

This grade has high strength, hardness (up to 300O C/ 572O F) and corrosion resistance.After heat treatment,

the mechanical properties of the product are more perfect, which can reach the compressive strength of up to 1100-1300 MPa (160-190 ksi).
